Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to solve the above-mentioned problems, a driving assistance prompting method based on a vehicle approach route according to the embodiment of the present application will be described and illustrated in detail by the following specific embodiments.
Referring to fig. 1, a flow chart of a driving assistance prompting method based on a vehicle trip route according to an embodiment of the present application is shown.
In an embodiment, the method is applicable to a vehicle-mounted terminal, the vehicle-mounted terminal can be in communication connection with a cloud server, the cloud server can be used for data statistics, storage, auxiliary analysis and other functions, and the vehicle-mounted terminal can be used for data calculation, data analysis, driving auxiliary prompt and other functions.
Wherein, as an example, the driving assistance prompting method based on the vehicle pass route may include:
s11, after a long-term parking point of a vehicle is determined, a plurality of first pass routes related to the long-term parking point are determined.
Referring to FIG. 2, a schematic diagram of a vehicle pass route is shown, provided in an embodiment of the present application.
In an embodiment, the vehicle-mounted terminal may send an instruction for acquiring the long-term parking point to the cloud server, so that the cloud server sends the long-term parking point set by the user to the vehicle-mounted terminal according to the instruction or sends the long-term parking point obtained through calculation and analysis to the vehicle-mounted terminal.
After determining the long-term parking point, the vehicle-mounted terminal can send an instruction to the cloud server, so that the cloud server uses the long-term parking point as a starting point, and calculates routes corresponding to the rounds of the vehicle running back and forth for many times by using the long-term parking point as the starting point, thereby obtaining a plurality of first rounds of routes.
Or after determining the long-term parking point, the vehicle-mounted terminal records the driving route of the vehicle through the GPS positioning technology of the vehicle-mounted terminal, searches a plurality of driving routes to obtain a route which is driven by taking the long-term parking point as a starting point and a terminal, and obtains a plurality of first-pass routes.
As shown in fig. 2, the user starts from the long-term stop point and then returns to the long-term stop point after traveling, and this is a round trip, and the travel route is a first-pass route.
It should be noted that the first paths may be the same or different from each other.
In an embodiment, the step of determining the long-term parking point of the vehicle may be performed by a vehicle-mounted terminal, or may be performed by the vehicle-mounted terminal triggering the cloud server, and may be specifically defined according to actual needs.
As an example, step S11 may include the following sub-steps:
s111, selecting a plurality of stop places of the vehicle in a preset driving range through a GPS positioning mode, and counting the stop times of each stop place to obtain a plurality of stop times values.
In practical applications, the long-term parking point of the user may be a residential parking lot or a corporate parking lot of the user, and the parking space in the parking lot may not be fixed, so that the place where the vehicle is parked each time may be different, but the area is an area where the user parks the vehicle for a long period of time.
For this purpose, a predetermined driving range (for example, 1-3 km, preferably 2 km) can be set. An area can be set by taking a place set by a user as a center and taking a preset driving range as a radius, and then coordinates of a plurality of parked vehicles of the user in the area are acquired through a GPS positioning mode, so that a plurality of parked places are obtained.
The number of stops per stop, for example, within a month, or within a week, may then be counted.
S112, selecting a plurality of parking places as long-term parking points based on the numerical value of the parking times.
If the number of stops at the stop point is small, the stop point is possibly a temporary stop, and is not a long-term stop point of the user.
The method can screen a plurality of stopping points meeting the preset stopping times from a plurality of stopping points based on the stopping times, and takes the stopping points meeting the preset stopping times as long-term stopping points.
For example, a number of stop places with a stop number greater than 10 are screened as long-term stop points. For another example, the first 10 stop points with the largest stop number can be ranked as high as the bottom stop number, and then screened as long-term stop points.
S12, determining overlapping areas of a plurality of first-pass routes to obtain overlapping routes, and calculating a fuel consumption value when the vehicle runs based on the overlapping routes to obtain a reference fuel consumption value.
In an embodiment, after determining a plurality of first-pass routes, overlapping areas between every two of the plurality of first-pass routes may be obtained to obtain a plurality of overlapping routes, and then one of the overlapping routes is arbitrarily selected as an overlapping route for subsequent processing and calculation.
Referring to fig. 3, a schematic diagram of a vehicle coinciding route is shown according to an embodiment of the present application.
Assuming that there are two long-term parking points, a and B, respectively, each corresponding to one first pass route, there are two first pass routes in total. Then, the overlapping portion of the two first-pass routes may be searched, as shown in fig. 3, and if the connection line between a and B is the overlapping portion, the connection line between a and B may be used as the overlapping route.
After the determination of the coinciding route, the actual fuel consumption of the vehicle traveling in the coinciding route may be calculated.
Because the road sections of the coincident routes are the same and the user has to travel through the routes each time, the road condition and the traveling elevation of the user can be determined to be the same. The method can carry out subsequent oil consumption calculation based on the same environmental conditions, can be more fit with the actual application situation of a user, and can be matched with different trip routes, so that the error of the subsequent oil consumption calculation can be reduced, and the accuracy of calculation is improved.
In an alternative embodiment, there may be multiple long-term parking points, there may be multiple corresponding first-pass routes, and there may be multiple routes in the overlapping area between every two of the multiple first-pass routes, so that there are multiple overlapping routes, and in order to further screen out the overlapping routes similar to each first-pass route or fit the overlapping routes of different first-pass routes from the multiple overlapping routes, so that the environmental conditions and road conditions of the overlapping routes can be matched with the different first-pass routes, and the accuracy of the subsequent fuel consumption calculation is further improved.
As an example, step S12 may include the following sub-steps:
s121, determining a plurality of routes overlapped with each other between every two of the first-pass routes to obtain a plurality of overlapped routes.
Specifically, a plurality of first-pass routes can be overlapped with each other to obtain a plurality of overlapped routes.
Assuming that there are three long-term parking points, A, B and C respectively, and each long-term parking point corresponds to one first-pass route, then there are three first-pass routes in total, two first-pass routes corresponding to a and B can be determined to be mutually overlapped, two first-pass routes corresponding to a and C can be determined to be mutually overlapped, and two first-pass routes corresponding to B and C can be determined to be mutually overlapped, so that 3 overlapped routes are obtained in total.
If there are two or more first routes per long-term stop, multiple superimposed routes may also be obtained by operating in the manner described above.
S122, acquiring a driving parameter of each overlapped route, and carrying out aggregation classification on a plurality of overlapped routes according to the driving parameter to form a plurality of route categories, wherein each route category comprises at least one overlapped route, and the driving parameter comprises: running conditions, running road conditions and running environment.
In an embodiment, the driving parameters may include driving conditions, driving road conditions, driving environment, weather information, humidity, temperature, wind direction, etc. corresponding to each time of occurrence may be added. And carrying out aggregation classification on each superimposed route according to each parameter, and identifying similar passes so that the superimposed routes with the same driving parameters are integrated together. The classified routes are identical in driving road sections and weather, temperature and humidity and environment, so that the influence of road conditions and environmental factors on oil consumption can be reduced, and the accuracy of subsequent oil consumption calculation is improved.
S123, selecting a superposition route of the route categories as a superposition route.
Since the conditions of the routes of the respective categories are the same, any one superimposed route of one category can be arbitrarily selected as the superimposed route.
If the distance traveled by the coincident route is long, the following fuel consumption may have more influencing factors, for example, the driving habit of the user or an emergency, so as to further reduce the influence of the factors, in an alternative embodiment, step S123 may include the following substeps:
s1231, calculating the vehicle driving distance corresponding to the superimposed route of each route category, and obtaining a plurality of driving distance values.
S1232, selecting a travel distance value with the smallest value from the travel distance values, and taking the superimposed route corresponding to the travel distance value with the smallest value as the combined route.
Specifically, the vehicle travel distance corresponding to the superimposed route of each route category, that is, the mileage of the route, may be calculated, so that a plurality of travel distance values may be obtained.
And screening the travel distance value with the smallest value from the travel distance values, and taking the superimposed route corresponding to the travel distance value with the smallest value as the combined route.
Alternatively, the travel distance value with the largest value may be selected from the plurality of travel distance values according to the actual application requirement, and the superimposed route corresponding to the travel distance value with the smallest value is the merged route.
Alternatively, the number of vehicle driving times corresponding to the superimposed route of each route category may be calculated according to the actual application requirement, the number of vehicle driving times with the largest value may be selected from the plurality of vehicle driving times, and the superimposed route corresponding to the number of vehicle driving times with the smallest value may be the superimposed route.
It should be noted that, in order to reduce the burden of processing data by the vehicle-mounted terminal, in an embodiment, the vehicle-mounted terminal may send the determined first time route to the cloud server, the cloud server determines the superimposed route, and then sends the superimposed route to the vehicle-mounted terminal. And then, the vehicle-mounted terminal can combine a plurality of routes recorded in advance by the cloud server and the transmitted overlapped route to carry out aggregation classification, so that the overlapped route is obtained by screening.
After the coincident route is determined, the fuel consumption value of the vehicle when traveling can be calculated based on the coincident route.
In an embodiment, the way to calculate the reference fuel consumption value may comprise the sub-steps of:
s21, randomly selecting one first-pass route from a plurality of first-pass routes contained in the overlapped route, and taking the oil consumption value of the randomly selected first-pass route as a reference oil consumption value.
In an embodiment, one first-pass route may be arbitrarily selected from the first-pass routes corresponding to the overlapped route, and then the fuel consumption value of the one first-pass route is used as the reference fuel consumption value.
Specifically, the fuel consumption value of the first-pass route on the coincident route may be used as the reference fuel consumption value.
Or alternatively;
s31, screening the highest fuel consumption value from the fuel consumption values of the first time routes corresponding to the overlapped routes to obtain a reference fuel consumption value.
In an embodiment, the fuel consumption value of each first route corresponding to the overlapped route may be calculated, and then the fuel consumption value with the largest value is selected as the highest fuel consumption value, and the highest fuel consumption value is used as the reference fuel consumption value.
Or alternatively;
s41, screening the lowest fuel consumption value from the fuel consumption values of the first time routes corresponding to the overlapped routes to obtain a reference fuel consumption value.
In an embodiment, the fuel consumption value of each first route corresponding to the coincident route may be calculated, and then the fuel consumption value with the smallest value is selected as the lowest fuel consumption value, and the lowest fuel consumption value is used as the reference fuel consumption value.
Or alternatively;
s51, screening a plurality of oil consumption values from the oil consumption values of a plurality of first-pass routes corresponding to the coincident routes according to a preset oil consumption value, and calculating the average value of the plurality of oil consumption values to obtain a reference oil consumption value.
In an embodiment, the fuel consumption values of the first route corresponding to the overlapped route may be screened according to the preset fuel consumption number value, and then the average value of the fuel consumption values is calculated to obtain the reference fuel consumption value.
For example, the first-pass routes corresponding to the overlapped routes may be screened for the first 10 first-pass routes, then the fuel consumption data corresponding to the first 10 first-pass routes may be obtained, and then the average may be calculated to obtain the reference fuel consumption value.
Or alternatively;
s61, screening a plurality of oil consumption values from the oil consumption values of a plurality of first-pass routes corresponding to the overlapped route according to the running time sequence of the plurality of first-pass routes, and calculating the average value of the plurality of oil consumption values to obtain a reference oil consumption value.
In an embodiment, the first time routes corresponding to the overlapped routes may be arranged according to the running time sequence, specifically, the first row of the latest running and the last row of the following running may be arranged according to time sequence.
And then screening a plurality of first-pass routes according to a preset number value to obtain the oil consumption value of each first-pass route, and then solving the average value of all the oil consumption values to obtain the reference oil consumption value.
For example, the last 10 first-pass routes in the coincident routes may be screened, then the fuel consumption values of the last 10 first-pass routes may be obtained, and then averaged to obtain the reference fuel consumption value.
Or alternatively;
and S71, screening a plurality of oil consumption values from the oil consumption values of a plurality of first-pass routes corresponding to the overlapped route according to the running time sequence of the plurality of first-pass routes, and carrying out weighted average calculation on the plurality of oil consumption values to obtain a reference oil consumption value.
Optionally, a plurality of corresponding first-pass routes may be screened in the above manner, and the fuel consumption value of each first-pass route is obtained, and then the fuel consumption values are weighted and averaged to obtain the reference fuel consumption value.
For example, the last 10 first-pass routes in the coincident routes can be screened, then the oil consumption values of the last 10 first-pass routes are obtained, and weighted average calculation is performed on the 10 oil consumption values to obtain the reference oil consumption value.
In an alternative embodiment, the operation of weighted average calculation may comprise the sub-steps of:
s711, clustering the fuel consumption values by adopting a K-means algorithm to obtain a plurality of fuel consumption categories, wherein each fuel consumption category comprises at least one fuel consumption value.
And S712, counting the number value of the fuel consumption value contained in each fuel consumption category, and converting the number value into a weight value according to a preset proportion value.
S713, calculating a reference fuel consumption value by adopting the fuel consumption value of each fuel consumption category and the corresponding weight value.
Taking the above example, assume that the last 10 first-pass routes in the coincident routes are screened, and then the fuel consumption values of the last 10 first-pass routes are obtained, so as to obtain 10 fuel consumption values.
The 10 fuel consumption were clustered by a K-means algorithm, optionally with k=3, into 3 classes. Meanwhile, the class sequence number and the number of passes of the class can be recorded.
Next, this actual fuel consumption=fuel consumption of the reference trip=sum (fuel consumption of the first trip route×weight)/Sum (each trip weight).
Wherein the weight of each first pass route = the number of passes of that pass sequence number/10.
Alternatively, the mileage can be calculated, and the fuel consumption can be calculated according to the mileage.
The mileage is calculated as follows:
mileage of reference pass = Sum (pass mileage weight)/Sum (each pass weight);
the number of event occurrences of the reference pass=sum (number of event occurrences of pass) Sum (weight of each pass) is rounded.
It should be noted that, during the calculation, abnormality detection may also be performed, for example, whether other factors such as a certain parameter is abnormal=pass normal is weighted: normal ratio, pass anomaly weight: and (3) judging the abnormal proportion and judging the proportion of the normal and abnormal is large, and determining whether the reference pass is normal or not.
If the calculation is abnormal, the vehicle-mounted terminal can inform the user.
S13, after a second trip route of the vehicle is obtained, calculating an oil consumption difference value of the reference oil consumption value and an oil consumption value corresponding to the second trip route, and carrying out driving assistance prompt according to the oil consumption difference value, wherein the second trip route is a route which is different from the first trip route and is currently driven by the vehicle.
In an embodiment, the calculated reference fuel consumption value may be the fuel consumption of a certain section of the coincident route of a certain trip, or the fuel consumption of a whole section of the path of a certain trip, and if the current trip of driving the vehicle is not changed, the fuel consumption is not changed in a large probability, and the fuel consumption reminding may not be performed.
If the current driving time of the vehicle is changed, the fuel consumption of the current time route may be different from that of the previous time route, and fuel consumption reminding needs to be performed. For this purpose, the vehicle travelled by the user can be located by means of GPS technology, and it is checked whether the route travelled is identical to the route of the previous trip.
